Examination
1. The ELD system detects signs of overload of the electrical circuits of the external lighting and signaling devices, fuel injection, charging, etc. The first symptom of such overloads is a violation of the stability of the power supply at idle speed of the engine. Failure of the detector leads to recording of the fault code P1297 or P1298 in the memory of the self-diagnostic system.
2. Remove the ELD (see paragraph 1 below) and disconnect the wiring harness from it. Measure the voltage between terminal 1 (+) and ground on the harness side connector with the ignition on (do not start the engine). The nominal value is equal to battery voltage. If there is no voltage, check the condition of the wiring harness between the 15 A fuse #6 and the detector.
3. With the ignition on (do not start the engine), measure the voltage between terminal 3 (+) and ground on the connector on the harness side. The required value is 4.5÷5.0 V. If the required result is not obtained, check the condition of the ELD wiring between the engine and the generator.
4. Check for continuity between terminal No.2 and ground.
5. If the above checks fail, replace the ELD unit.
Replacement
1. The ELD unit is located inside the fuse/relay box in the engine compartment of the vehicle. Disconnect the negative battery cable.
Warning! If the car stereo system is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery!
2. Remove the two mounting screws, remove the ELD unit from the center of the mounting block and disconnect the electrical wiring from it.
3. Installation is carried out in reverse order.
